Im just wondering 23ins was a Diffrent world a spinoff from the cosby show and after denise left was it still a spinoff from the cosby show and How come when Lisa Bonet got pregnent wht did they take her of a diffrent world and put her back on the cosby show?

After watching those "True Hollywood Stories" ad infinitum on E!, perhaps I can shed some light on this: Lisa Bonet, to put it mildly, could sometimes be a handful on the show. Unlike all the other Cosby kid actors, she really didn't have a sense of personal responsibility towards the show and was often late/never showed up. Cosby, who was very demanding with the Cosby cast, did show some leniency towards her, and offered her the "Different World" spinoff (which gave her some freedom in her "own" show). Well, during "A Different World", Lisa Bonet became pregnant, starred in a controversial film, much to Cosby's dismay. I don't think she was "fired" from "A Different World", more like "Dismissed", because Cosby did have a place for her on "The Cosby Show" when she was ready to return. Bonet left "The Cosby Show" the second time on her own accord to explore other projects, but all in all, once she left that time, I think she pretty much knew she wouldn't be welcomed back. "A Different World" is still a spin-off of "The Cosby Show", even without Denise, because Claire and Cliff did make appearances on the show even after Denise was gone.
